Product Description

The main purpose of hard black anodised aluminum is to improve the performance of aluminum and aluminum alloy, including corrosion resistance, wear resistance, weather resistance, insulation and adsorption. Hard black anodised aluminum is suitable for deformation of aluminum alloy, can also be used for die-casting aluminum alloy parts. The oxide film of Anodised aluminum parts generally requires a thickness of 25-150μm, the thickness of oxide film of most anodised aluminum parts is 50-80μm, anodised aluminum parts with a thickness of less than 25 μm are used for parts such as gear keys and spirals. The oxide film of anodised aluminum parts for abrasion or insulation is about 50μm thick, under certain special process conditions, it is required to produce anodised aluminum parts with an oxide film thickness of more than 125μm, However, it must be noted that the thicker the anodic oxide film is, the lower the microhardness of the outer layer is and the roughness of the film surface increases.
